Abstract

The invention discloses an intelligent vehicle speed control and management system and an implementing method thereof. Through installation of the system, the driving speed of a driver can be effectively and reasonably controlled, so that the vehicle speed is automatically controlled within the required speed-limiting range. The intelligent vehicle speed control and management system can manage the identity information of different users and allow different drivers to possess respective speed limit and other database information, and after successful verification, different drivers can log in respective vehicle speed control and management systems. The intelligent vehicle speed control and management system comprises an autonomous driving control module, a normal speed driving module, an automatic constant-speed driving module and an overspeed driving module (including an automatic slowdown module and a forced slowdown module), which are interconnected with one another, and the respective corresponding modes and statuses are mutually switchable, so that the vehicle speed can be controlled to ensure the driving security.

Description

technical field

[0001] The patent of the present invention relates to a vehicle speed control method, in particular to an intelligent vehicle speed control management system and its implementation method. Background technique

[0002] Because different roads have different requirements for the speed limit of vehicles, it is difficult for the current speed limit control system to limit the speed of different roads. For example, the speed limit ranges of expressways, urban roads, and different lanes are different. Different roads have separate speed limits.

[0003] At present, the recognition rate and recognition performance of the system that uses a camera to recognize speed limit signs is not high, it is easily affected by weather changes, and it is expensive.

[0004] At the same time, the existing speed limit control system is not based on the current real-time road speed limit information, but only controls the maximum speed limit value; at the same time, the current ve...

Examples

specific Embodiment approach

[0127] In order to further illustrate the specific implementation of the patent of the present invention, the special work is as follows to illustrate its work process:

[0128] 1. First, verify the user's identity and pass it (according to the user ID information, the user's speed limit can be found in the database of the vehicle speed control management system);

[0129] 2. Read the coordinate data of the GPS sensor to obtain the current location information of the car. The coordinate data is directional vector information.

[0130] 3. According to the GPS coordinate position vector information, calculate which vector road the current location belongs to, query in the vector road-speed limit table of the road speed limit database, and find the corresponding speed limit value range Vgpsmin~Vgpsmax (general roads only have The maximum speed limit value, a few have the minimum speed limit value information).

[0131] 4. According to the current user ID information and the curr...
